#### Zabbix agent 2 plugins

For Ceph, Docker, Memcached, MySQL, Oracle, and Redis plugins, a Uri can
no longer be specified as a 1st level plugin parameter. For PostgreSQL
plugin a Uri and Database name can no longer be specified as a 1st level
plugin parameters. Now these parameters can only be provided at a named
session level. All existing parameters in a format
Plugins.<PluginName>.Uri and the Plugins.Postgres.Database
parameter should be removed from the configuration file, otherwise, the
agent will fail to start.

For Uri parameters, specifying a scheme is no longer mandatory.

For the default set of parameters, you can create a named session
'Default' and specify these parameters in the session. See an example
below.

|Before Zabbix 5.0.7|Since Zabbix 5.0.7|
|-------------------|------------------|
|Plugins.Ceph.Uri="https://localhost"|Plugins.Ceph.Sessions.Default.Uri=localhost|
